新型有机-无机杂化多孔分子筛在干胶转化条件下的一步可控自组装合成及在有机催化中的应用研究

有机-无机杂化多孔分子筛因在选择性吸附和催化领域的独特性能而引起人们极大的研究兴趣；然而，其传统合成方法具有制备过程周期长且难于控制、有机功能基团含量低、有机模板剂去除困难等问题，阻碍了这类材料更广泛深入的应用研究。基于本课题组长期工作积累和前期取得的研究结果，本项目将以有机催化应用为导向，利用有机功能基团种类丰富、易于化学改性的特点和无机分子筛骨架结构组成丰富、富于调变的性质，通过运用和发展干胶转化合成策略，一步自组装合成新型有机-无机杂化多孔分子筛催化剂材料，充分开发其独特的催化应用效能，实现高效的、可比拟于均相催化效率的多相有机催化转化，探究干胶转化条件下一步自组装可控合成机制，为设计合成高效的杂化类分子筛功能材料提供理论指导和技术支持，符合绿色化学的要求，对实现节能减排具有重要理论和实际意义。

Owing to the unique properties in selective adsorption and catalysis, organic-inorganic hybrid molecular sieves have aroused great interests of chemists. However, the conventional synthesis methods of organic-inorganic hybrid molecular sieves have several disadvantages, such as the uncontrollable preparation process, long crystallization period, quite low organic group content, difficulty in the removal of organic template, and so on, which influence the extensive and deep studies of this kind of materials. The research interests of our group have focused on the synthesis, characterization and catalytic application of molecular sieves and organic-inorganic hybrid functional materials for many years. In the proposal, directed by the applications in catalytic organic reactions, controllable self-assembly dry-gel conversion method is used to synthesis novel organic-inorganic hybrid molecular sieves with excellent catalytic ability. The success attainment of the proposal will provide useful direction and powerful support for the design and synthesis of functional materials with excellent catalytic properties in theories and in techniques, which is meaningful for the energy saving and emission control.
